Renee Zellweger | Bridget Jones | Gained: 20 lbs

Bridget Jones Diary superstar Renee Zellweger is all about staying fit and healthy, but while she was preparing for her credit role as Bridget Jones, she had to eat up fatty and carb-filled food, like doughnuts and pizzas. However, right after the filming for the movie was over, she quickly stopped her 4,000 calorie intake a day, slimming down in a matter of months.

She follows a strict diet, only eating lean fish and vegetables, with a little bit of rice. She wouldn’t be on the list of 50 Most Beautiful People if she doesn’t maintain her figure and take care of her good looks. She is big on workouts and she loves going to the gym, finding it therapeutic. Renee spends six days a week doing intense cardiovascular workouts. She is an inspiration to a lot of women out there.
